As part of my ongoing work on multi-touch, I have been looking at handling touch gestures within Mutter plugins. Developing a X window manager/shell can be quite a hassle because you are likely to want to do that in a separate X display so your testing doesn't disturb the session where you do the actual coding.
In the past I have used Xephyr to run a nested X display so I can run the window manager as I would run any normal application, but this time I found that Xephyr doesn't forward any XInput2 events right now, which is needed for MT. Having a separate machine where to test is an alternative but it has been quite uncomfortable.
My colleague at Collabora Daniel Stone encouraged me to give it a try and it indeed didn't take much work to get something running, though I still haven't tested it much.
So for the code, here is the Xephyr repo: http://cgit.collabora.com/git/user/tomeu/xserver/log/?h=xephyr-touch
And here the Mutter repo: http://cgit.collabora.com/git/user/tomeu/mutter/log/?h=touch-clutter
Remember that these are early proof-of-concepts, but if you give it a try and want to give feedback, it will be welcome.
As usual, thanks to my employee Collabora for sponsoring this work and letting me share it.
